Could we have a method (not a tax system but something close) where people running missions/arcade when they loot crowns a percent is created and automatically deposited into the Guild Treasury.
example: I run Vana and loot a total of 7,000 crowns. a percent (say 5%) is created and then deposited into the Guild Treasury. In this example it would be 350 crown. (7k * 0.05).
I'm thinking automatically created because I don't feel a tax (thus removal of the funds from the player) is a good thing. This could be an upgrade that has to be purchased and thus could be easily made back. The percentage could be increased for an additional price.
5% - 50,000 crowns (for those eu people that's 50.000)
10% - 120,000 crowns (eu 120.000)
*Note the prices listed are just examples.
This could be a better incentive to get guild members together to run the clockworks.
So, what you are saying is that we should be able to tax our guildmates?
Sounds like you want to start a government system of some sort.
As for getting people back into the clockworks, it'll just become more of a ghost town, because people don't like taxes overall.
EDIT: We don't need taxing. People can put in their own money in their treasury whenever they feel like it. I'm fine with that.
